Overview
The Open Quantum Materials Database (OQMD) is a comprehensive database containing the thermodynamic and structural properties of over 1.4 million materials, calculated using Density Functional Theory (DFT). Developed at Northwestern University, it serves as a valuable resource for researchers and scientists in materials science, chemistry, and physics. OQMD allows users to search for materials based on composition, query specific properties, create phase diagrams, and visualize crystal structures. The database is designed to facilitate the discovery of new materials and the understanding of existing ones, enabling accelerated materials design and development. The OQMD is licensed under CC-BY 4.0, promoting open access and collaboration within the scientific community. It provides both a web interface and a RESTful API for accessing the data.
